(1) by reserving a treatment channel, medicament injection or stem cell transplantation can be directly performed in subsequent treatment of electrical stimulation, so that a new wound is avoided, and the medicament or stem cell transplantation is conveniently matched with nerve electrical stimulation to treat diseases;

(2) the opening and closing of the treatment channel are realized by the plug-in matching of the outer sleeve and the inner catheter, and particularly the treatment channel is well sealed when the outer sleeve and the inner catheter are not used;

(3) the guide rail guide groove structure is used for guiding the plugging and unplugging of the inner guide pipe so as to ensure the axial alignment of the alignment hole and the side hole which can be opened and closed, and particularly when a control nut is used for plugging and unplugging control;

(4) the insertion guide of the treatment tube is realized through the design of the inclined closed bottom plate, so that the operation is more convenient and accurate;

(5) the cooperation between the control nut, the inner catheter and the outer sleeve is convenient for the upward pulling of the inner catheter and the control of the upward pulling length.

Detailed Description

The invention is described in detail below with reference to the drawings and examples of the specification:

fig. 1 to 4 are schematic diagrams of an embodiment of a reserved treatment channel electrical nerve stimulation device provided by the invention.

A nerve electrical stimulation device with reserved treatment channels comprises an outer sleeve 2 arranged in an implanted electrode 1 and an inner catheter 3 which is nested in the outer sleeve 2 and can only be axially inserted and pulled relative to the outer sleeve 2; the lower part of the outer sleeve 2 is provided with a side hole 4 which can be opened and closed; the implantation electrode 1 is provided with a communicating hole 5 which is correspondingly communicated with the openable side hole 4; the side wall of the bottom end of the inner catheter 3 is provided with an alignment hole 6 matched with the side hole 4 capable of being opened and closed, and in the process that the inner catheter 3 is pulled out upwards, the alignment hole 6 and the side hole 4 capable of being opened and closed are completely staggered to be completely aligned; the bottom end of the inner conduit 3 is provided with a closed bottom plate 7.

The side hole 4 capable of being opened and closed is a through hole controlled to be opened and closed by the valve type sealing structure, the valve type sealing structure is utilized to facilitate the insertion of the treatment tube, and the treatment tube is wrapped to improve the sealing property when the treatment tube is inserted.

The outer sleeve 2 and the inner guide tube 3 are pulled out and inserted and guided through an axially extending guide rail guide groove structure 8.

In order to facilitate the insertion and removal of the inner tube 3, an axially extending air channel 9 is provided in the guide track structure 8.

The closed bottom plate 7 is an obliquely arranged bottom plate, and the lowest point of the closed bottom plate is positioned on one side of the aligning hole 6.

The upper end of the outer sleeve 2 extends out of the implantation electrode 1; the upper end of the outer sleeve 2 is in threaded connection with a sealing positioning cover 10; the sealing and positioning cover 10 seals the upper port of the inner conduit 3. The inner catheter 3 is sealed by the sealing and positioning cover 10, and the inner catheter 3 is pressed and positioned at the same time, so that relative displacement between the inner catheter and the outer cannula 2 is avoided.

The upper end of the inner catheter 3 extends out of the outer sleeve 2; the outer wall surface of the upper end of the inner conduit 3 is sleeved with a control nut 11 which is in threaded connection with the inner conduit 3 and is abutted against the upper end of the outer sleeve 2 so as to pull up the inner conduit 3.

At the lower limit of the movement of the control nut 12 relative to the inner conduit 3, the outer wall surface of the inner conduit 3 is provided with an indicator line 12 aligned with the upper end surface of the control nut 11.

The method of use of this example is as follows:

(1) screwing off the sealing positioning cover 10, and correspondingly cleaning and disinfecting the inner catheter 3;

(2) screwing the control nut 11 outside the inner catheter 3, and pushing the control nut 11 against the outer sleeve 2 by rotating to pull out the inner catheter 3;

(3) when the control nut 11 is screwed to the lower limit (i.e. the upper end face of the control nut 11 is aligned with the indicating line 12), the alignment hole 6 is aligned with the side hole 4 which can be opened and closed (see fig. 1 and 2);

(4) a treatment tube is inserted into the inward catheter 3, and the treatment tube sequentially passes through the alignment hole 6, the openable side hole 4 and the communicating hole 5 to enter a human body under the inclined guidance of the closed bottom plate 7 so as to carry out medicament injection or stem cell transplantation;

(5) after the treatment is finished, the treatment tube is pulled out, the control nut 11 is screwed out, the inner catheter 3 is inserted downwards, the alignment hole 6 and the side hole 4 which can be opened and closed are completely staggered, and then corresponding cleaning and disinfection are carried out;

(6) the sealing and positioning cap 10 is screwed back to the outer sleeve 2 (see fig. 3) to perform sealing and positioning.
